浙江省环境中氚放射性水平调查

Investigation of Environmental Tritium Radioactivity Level in Zhejiang Province

本文介绍了1988～1993年浙江省环境中氚放射性水平调查结果.杭州湾和舟山海域海水氚浓度分别为2.1Bq/1和1.8Bq/l;湖水、河水和塘水氚浓度分别为1.6Bq/l、1.8Bq/1和3.0Bq/l:雨水和大气凝结水氚浓度分别为2.1Bq/l和2.2Bq/l;松针组织自由水氚浓度为2.5Bq/l.调查结果表明,浙江省环境未受到核试验外其他人为活动氚的污染.

The results of environmental tritium radioactivity level investigation in Zhejiang Province from 1988-1993 were showed. The tritium concentrations of seawater in Hangzhou Bay and Zhoushan Islands were 2.1Bq/l and 1.8Bq/l. The tritium concentrations of lake water, river water, pond water, rainwater and atmospheric vapour condensates were 1.6 Bq/1, 1.8Bq/l, 3.0Bq/l, 2.1Bq/l and 2.2Bq/l respectively. The tritium concentration in the free water of pine needle tissue was 2.5Bq/l. The data indicated that environment of Zhejiang Province was not polluted from tritium produced by human activities except for nuclear test.
